Foundry casting ha se feela ho tšela tšepe e qhibilihisitsoeng ka har'a hlobo. Ke moo mahlale a lintho tse bonahalang a kopanang le taeo e leka-lekaneng - 'me moo motho a hatetseng moralo o fosahetseng, khetho ea alloy, kapa sekhahla sa ho pholisa se ka jang libeke ho sebetsa bocha, eseng lidolara feela. Ho QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., re kentse li-valve tsa khatello tse fetang 12,000 le li-cylinders tsa pompo ea piston ho tloha ka 2018-e 'ngoe le e 'ngoe e na le mamello e thata ka tlase ho 0.05 mm mme e pholohile 300+ bar hydraulic cycles. Phihlelo eo e re rutile ntho e 'ngoe ea bohlokoa: ho qaptjoa ka nepo ha sebōpi ho qala nako e telele pele sebōpi se tuka.
Moralo oa ho Lahla—Eseng Bakeng sa Mosebetsi Feela
Hangata lienjineri li ntlafatsa likarolo tsa eona bakeng sa ho kopanya kapa ho ajoa ha khatello ea maikutlo—ebe li fana ka litšoantšo tse lebeletseng hore li-casters li “sebetse.” Empa lehlabathe le matsete a lichelete li na le meeli e thata ea 'mele. Re kile ra fumana faele ea CAD bakeng sa ntlo ea pompo ea cobalt-alloy e nang le likarolo tsa marako a 2.3-mm le likhopo tse ka hare tse arohaneng ka 4.7 mm. Karolo e ile ea robeha nakong ea ho sisinyeha—e seng ka lebaka la ho se tšolle hantle, empa ka lebaka la hore likhahla tsa mocheso li ne li feta fensetere e tiileng ea AMS 5387. Re ile ra fetola likhopo tsa geometry, ra eketsa libaka tse batang tsa sebaka seo, eaba re suthisetsa khoele ea ho arohana ka likhato tse robeli. Kotulo e tlohile ho tloha ho 62% ho ea ho 98%.
Litlhahlobo tsa bohlokoa tseo re li etsang pele re qotsa:
- Botenya ba karolo e fokolang: ≥4.5 limilimithara bakeng sa castings tšepe, ≥3.2 limilimithara bakeng sa cobalt-nickel alloys joaloka T800
- Karolelano ea radius ho lebota: Likhutlo tse ka hare li tlameha ho ba ≥0.6 × botenya ba lebota bo haufi ho qoba meokho e chesang
- Undercut tolerance: Mefuta ea lehlabathe e mamella ≤15 ° moralo; mekhoa ea lichelete e hloka ≥0.5 ° ka lehlakoreng le leng-kapa li-cores tse entsoeng ka CNC
- Ho itšehla thajana: Qoba baokameli ba masesaane, ba itšehlang thajana kapa li-flanges - li pholile ka potlako, li suthela hōle le lisebelisoa tse ngata, 'me li bula litsela tse nyenyane tse honyehang.
Haeba GD&T ea hau e hloka boemo ba 'nete holim'a karolo e lahliloeng ka kotloloho ka har'a hlobo, netefatsa hore na sebaka seo se tla etsoa ka mochini. Re kenya 87% ea lisebelisoa tsa rona tsa tšepe le litšepe ho fihlela sephetho sa ho qetela - hobane libaka tse hahelletsoeng ha se hangata li tšoarang ± 0.1 mm ho nepahala ha 300 mm.
Khetho ea Alloy e Fetola Ntho e 'Ngoe le E 'ngoe-Haholo-holo ha U sa khone ho e Sebelisa Hamorao
Li-alloys tsa cobalt-nickel tse kang AMS 5387 kapa T800 ha li khethoe bakeng sa aesthetics. Li hlakisoa ha khoholeho e hanana le khoholeho, matla a ho thella ka holimo ho 650°C, kapa ho sebetsa ka ntle ho makenete—joaloka ka har’a oli le likhase tse thellang kapa lirolara tse lebelo le phahameng tsa winch center. Empa thepa eona eo e etsa hore ho be thata ho e etsa mochini ka mor'a ho lahla. Plaka e le 'ngoe ea T800 e nka lihora tse 11.2 tsa ho sila ka li-multi-axis ho sebelisa lisebelisoa tsa PCD le sepholi sa cryogenic. Kahoo haeba karolo ea geometry e lumella, re kopanya machining ts'ebetsong ea ho lahla ka boeona-ho eketsa masoba a dowel, li-top datum pads, kapa esita le li-preforms tse sa fellang ka kotloloho molemong oa matsete.
Re fana ka li-ingots tsohle tsa superalloy tse nang le litlaleho tse felletseng tsa tlhahlobo ea leloala (MTRs) tse fumanehang ho nomoro ea mocheso le tlhahlobo ea lik'hemik'hale. Ha ho sehlopha se kenang seboping ntle le netefatso ea spectrographic. Hobaneng? Hobane ho kheloha ha 0.03% ho dikahare tsa khabone ho T800 ho fetola boima ba eona ho tloha ho 32 HRC ho ea ho 41 HRC - ho lekane ho pshatla sekheo sa carbide bohareng.
Boleng ha bo hlahlojoe ka har'a - bo hahiloe ka har'a, Lera ka Lera
Litsi tse ngata li lekola li-castings ka lintlha tse tharo: thepa e kenang, boemo bo thata ka mor'a ho sisinyeha, le tlhahlobo ea ho qetela ea pono. Re eketsa tse ling tse 'nè:
- Mold integrity scan: X-ray tomography ho 100% ea hlobo ea likhetla tsa matsete pele ho dewaxing
- Tšela tlaleho ea mocheso: Lintlha tsa nako ea sebele tsa thermocouple tse hokahaneng le nomoro e 'ngoe le e 'ngoe ea mocheso
- Sectional hardness mapping: Ho baloa ha Rockwell C ka lintlha tse 12 ho pholletsa le likarolo tse fapaneng tsa lotho e 'ngoe le e 'ngoe
- Hydrotest e sebetsang: 'Mele eohle ea li-valve tsa khatello e tlas'a khatello e lekantsoeng ea 1.5 × bakeng sa metsotsoana ea 120-e nang le kutloisiso ea ho lutla ho 0.003 cc/min
Re boloka ts'ebetso e felletseng - eseng feela bakeng sa liphuputso, empa hobane ha moreki a tlaleha ho putlama ha mokhathala ka lihora tse 14,200 tsa ts'ebetso, re ka hula thipa ea pele ea ho tšela, lekhalo la ho pholisa, le 'mapa o thata oa ka mor'a ho chesa mocheso ka tlase ho metsotsoana e 90. Lebelo leo le arola tokiso ea sesosa le khakanyo.
Hobaneng ha Hybrid Casting + Machining e Betla U le Mong
